Be it known that L @scams N.- iiosizv SON, a citizen of the United Saisies., swf. resident of Midland, commy of Midiand. und State of Michigan,'havc iiivcmcfi s nsw and useful :improvement in Fui-micas.. of Nhich the foliowing is s spccificsgion 3 principle of thc invention being contemplated sppiying; that pfriccciipics co s.; *c distinguish it from "cher iiwcusom.

The operation of the 'furnace constructed as just'described should be readily apparent. The `heated gases risiiig in stack #l pass .through the regulated openings '5, thence form, except that provision is made for .plurality of ducts in the heating chamber` :and the number of such chambers connected with a single combustion chamber is in' creased. to two.

Such combustion chamber 1l is accordingly somewhat larger in. proportion to the individual `heating chamber l2.. ot which latter only one is shown in` lull in the fig- 'ures` a corner of the second appearing in Fig. 3. The feature oi' a ballie 13 in the combustion chamber is retained. but. instead ot leading directly into the vertical stack 14,

and thence through the openings 15 which connect such stack with the heating chamber 12, the furnace chamber communicates with a transverse passage 1G extending in trout of both said chambers 12. lt. will he understood that by correspondiugly lengthening this passage 1li. any desired number ot'ihcating chambers may be connected therewith,A

depending upon the capacity of the combustion chamber. passage 16 and the vertical stacks 14 ot the respective heating chambers l2. is secured through a suitable duct 1T. best shown in li r. 4.

llisposed alongside each vertical stack 15 is a second stack 18 which, just as in the case. of stack in the previously described construction.` serves as they outlet for the spent gases. the latter being admitted to said stack through a series of openings i9. The several stacks itl are connected with a duct 21') through which such gases are finally cairied oil'.

lnsteadoic utilizing but a single duct for passing the material to be heated through chamber 12. a plurnlityof such ducts 21 is here employeiL one such duct. as before, passing approximately centrally through the chamber, and the others being symmetrically (`ommunication between thel grouped thereabout. As before, again utilize the feature of a radial partition 22 extending from a line on the Wall of the heating chamber between openings 15 andvertically throughout the chamber can be` secured. while the gases'. as before, are obliged to travel circularly around the chamber by reason of the partition 22.

Other modes of applying the principle of my invention maybe employed instead of the one explained. change 4being made as regards the mechanism herein disclosed, pro vided the means stated by anv of the following claims or the equivalent of `such stated means be employed.

l therefore particularly point out and distinctly claim -as my invention 1. ln a furnace of the character described, the conibination ot' a combustion chamber, a heating chamber. a stack, and a. duct for the material to be heated passing through said heating chamber. said combustion chamber being connected with said heating chamber by graduated openings whereby an approximately uniform temperature may be maintained throughout said heating chamber.

2. In a furnace of the character described, the combination of a combustion chamber, a heating chamber. a stack. and a duct for the material to be heated passing through said heating chamber. said heating' chamberl being connected with said stack by graduated openings whereby an approximately unilorm temperature. may be maintained throughout said heating chamber.
